Ghanaian motorists and households are likely to face marginal increases in petroleum prices from September 1, 2026, with petrol, diesel and liquefied petroleum gas (LPG) all projected to record higher pump prices despite a modest decline in global crude oil prices.
The projection by the Chamber of Petroleum Consumers (COPEC) points to a mixed international and domestic pricing environment in which the cedi’s appreciation against the US dollar has provided some relief, but increases in refined petroleum product prices have been strong enough to push expected retail prices upward.
COPEC’s September first-window assessment projects petrol at about GH¢16.21 per litre, representing a 5% increase over the current mean price of GH¢15.43 per litre.
Diesel is projected at GH¢17.61 per litre, while LPG is expected to reach approximately GH¢14.19 per kilogramme.
The projections are contained in a statement dated August 30, 2026, signed by COPEC Executive Secretary Duncan Amoah.
Refined Product Prices Offset Crude Decline
The projected increase in pump prices is notable because the international crude benchmark used in COPEC’s assessment actually declined marginally, falling from $90.41 per barrel to $89.30 per barrel.
Ordinarily, lower crude prices would be expected to ease pressure on petroleum prices.
However, crude oil is only one component of the pricing chain.
Refined product prices, exchange-rate movements, taxes, margins and other pricing elements can cause retail prices to move differently from crude benchmarks.
This is particularly evident in petrol.
COPEC estimates that the free-on-board (FOB) price of petrol increased from $1,033.15 per metric tonne to $1,136.50 per metric tonne, a 10% increase.
The increase in the refined product benchmark has therefore outweighed the benefit provided by the cedi’s appreciation.
The local currency improved from an average interbank rate of GH¢11.800 to the US dollar at the beginning of the current pricing window to GH¢11.5166 at the close, representing an appreciation of approximately 2.39%.
“Petroleum prices beginning Tuesday the 1st of September 2026 are expected to see some marginal increments across the pumps.”
Duncan Amoah, Executive Secretary, COPEC
The implication is that exchange-rate stability, while important, may not by itself guarantee lower pump prices when international refined-product benchmarks move sharply in the opposite direction.
For petrol consumers, COPEC expects prices to fall within a range of GH¢15.40 to GH¢17.02 per litre, allowing for a ±5% variation around its projection.
Diesel Faces Pressure Despite Stable Benchmark
Diesel presents a different picture.
COPEC’s assessment shows that the international FOB price of diesel barely changed, moving from $1,251.19 per metric tonne to $1,250.50, a decline of only 0.055%.
Yet the projected retail price is GH¢17.61 per litre, compared with a current mean price of GH¢17.17. That translates into an expected increase of 2.58%.
The result illustrates the importance of the exchange rate in Ghana’s petroleum pricing structure.
Even a virtually unchanged international product benchmark can translate into a higher local price depending on the interaction between currency movements and the other components of the domestic pricing formula.
COPEC projects a diesel price range of GH¢16.73 to GH¢18.49 per litre within its ±5% projection margin.
Diesel remains particularly important to the wider economy because it is heavily used in commercial transport, logistics, agriculture, construction and industrial activity.
Consequently, sustained increases in diesel prices can extend beyond motorists and affect the cost structure of businesses and, ultimately, consumer prices.
This creates an energy-policy concern for an economy attempting to strengthen industrial production and reduce operating costs.
LPG Price Rise Adds Clean-Cooking Pressure
LPG is also expected to increase marginally, with COPEC projecting a retail price of GH¢14.19 per kilogramme.
The international FOB price of LPG increased from $596 to $611 per metric tonne, representing a 2.64% rise.
Although the cedi appreciated by about 2.39%, the currency improvement was not sufficient to completely offset the international increase.
COPEC therefore projects a price range of GH¢13.48 to GH¢14.90 per kilogramme within its ±5% margin.
The LPG projection deserves particular attention because Ghana’s cooking-energy transition increasingly depends on the availability and affordability of LPG.
As previously highlighted in discussions around Ghana’s petroleum import trends, rising LPG demand reflects growing household and commercial consumption while domestic production remains insufficient to meet national requirements.
That makes the local LPG market particularly exposed to international prices and exchange-rate movements.
A marginal increase may appear limited at the individual household level, but repeated increases can influence the affordability of clean cooking, particularly for lower-income consumers.
Subsidy Decision Could Shape Consumer Impact
COPEC has consequently appealed to government to extend its subsidy intervention beyond the August deadline until global benchmarks return to what it considers normal levels.
The organisation has also urged oil marketing companies to maintain current ex-pump diesel prices in order to reduce pressure on consumers.
“COPEC would like to appeal to the government to extend its subsidy intervention beyond the August deadline until global benchmarks return to normalcy.”
Duncan Amoah, Executive Secretary, COPEC
The policy dilemma is straightforward but significant. Subsidies can shield consumers from sudden international price shocks, but prolonged fiscal support can also place pressure on government finances if maintained without a clear exit strategy.
For Ghana, the more sustainable response therefore lies not only in short-term price interventions but in strengthening the resilience of the petroleum supply chain, improving exchange-rate stability, increasing domestic refining capacity where economically viable and reducing excessive exposure to imported refined products.
The September projection ultimately demonstrates that falling crude prices do not automatically translate into cheaper fuel at Ghanaian pumps.
The refined-product benchmark, currency and domestic pricing conditions can be equally decisive.
With the first September pricing window approaching, consumers and businesses will therefore be watching not only crude oil markets but also refined-product prices and the cedi for signs of where fuel prices could move next.
